| Abstract |
|
Used and unused basking sites, food resources and nest site qualities of the turtle (Graptemys geographica) were quantified and compared within occupied bays and between occupied and unoccupied bays. Although the mean characteristics of used sites differed markedly from unused sites in the same bays, there were few differences between site characteristics in occupied and unoccupied bays. Discriminant function analysis of sites also indicated many suitable but unused sites in both occupied and unoccupied bays. Some food resources were greater in unoccupied bays, and typical quality nesting habitat was available in other bays. We concluded that the population was too small to occupy all available quality sites and hypothesize that social function was responsible for the distribution of turtles on used basking and nesting sites.
